 /**
  * filemap_write_and_wait_range - write out & wait on a file range
  * @mapping:	the address_space for the pages
  * @lstart:	offset in bytes where the range starts
  * @lend:	offset in bytes where the range ends (inclusive)
  *
  * Write out and wait upon file offsets lstart->lend, inclusive.
  *
  * Note that `lend' is inclusive (describes the last byte to be written) so
  * that this function can be used to write to the very end-of-file (end = -1).
